The specific embodiment
As shown in Figure 1, 2, fixed bearing framework 100 is to be made of the bearer frame on supporting leg 101 and the supporting leg 102; The beam the 103, the 104th of the both sides of bearer frame 102 has the channel-section steel that is oppositely arranged to constitute, and channel-section steel forms track.The end of fixed bearing framework 100 is provided with tow chain guided way 105 (as shown in Figure 3).
Shown in Fig. 4,5, floating shelf 200 comprises main frame 201, is connected with the permanent seat 202 of motor speed reducing driving device on the main frame 201, offers the output shaft hole 203 of motor speed reducing driving device on the permanent seat 202.The two ends that main frame 201 connects the beam of side are connected with roller 204 (shown in Figure 3).The axis 205 that has only shown roller among Fig. 4,5.Main frame 201 is provided with the adapter plate 206 of screw mandrel Connection Block.
As shown in Figure 1, motor speed reducing driving device 400 is fixed on the permanent seat 202 of floating shelf 200, and the output shaft of motor speed reducing driving device 400 is connected with and drives idler sprocket 401.
As shown in Figure 2, the beam 103 of fixed bearing framework 100 is provided with travel switch 109, and floating shelf is provided with two collision blocks 110 of travel switch.Two collision blocks are respectively applied for overload protection and chain rupture protection.
Again as shown in Figure 2, all be connected with floating shelf travel mechanism on the beam 103,104 of the both sides of bearer frame 102, be illustrated with the floating shelf travel mechanism on the beam 103.The end of beam 103 is provided with screw mandrel right support abutment 106, the polished rod pilot hole 301 of screw mandrel right support abutment 106 upper screw rods, and the stage casing of beam 103 is provided with screw mandrel left support abutment 107, establishes supported hole 108 (shown in Figure 6) on the screw mandrel left support abutment 107.Be fixedly connected with screw mandrel Connection Block 302 on the adapter plate 206 of floating shelf 200, screw mandrel 300 connects screw mandrel left support abutment 107, screw mandrel Connection Block 302 and screw mandrel right support abutment 106.
As shown in Figure 6, polished rod section 303 is provided with two spring perches 308,309, and prefastening force spring 310 is enclosed within on the polished rod section 303 between two spring perches.
Principle of work:
Tow chain passes from tow chain guided way 105, is connected with driving idler sprocket 401; Rotary screw rod 300 is moved to the left the nut of screw mandrel Connection Block 302, is moved to the left thereby drive floating shelf 200, will drive idler sprocket 401 and be connected tensioning with tow chain.When conveyer load had fluctuation or chain variable elongation, floating shelf made the system recovery balance by moving forward and backward the pressure of adjusting pressure spring.
When conveyer normally moves, the tractive force pulling force fluctuation range on the tow chain be operated in pressure spring to the tension range of tow chain in the time, floating shelf still is in state of equilibrium.So travel line changes the fluctuation of internal traction force at nominal situation conveyer is moved without any influence.When delivery system has impact load, moment the tow chain pulling force greater than tension force, this moment, floating shelf was moved to the left in the tow chain tension, pressure spring is compressed, and makes chain tension become big, the rebalancing chain pull, stable with operating mode, excessive chain tension promotes floating shelf to the right again, sets back, and keeps the conveyer stable operation.When conveyer transshipped, floating shelf was moved to the left until the overload protection collision block at the tow chain pulling force and touches travel switch, and conveyer is shut down.When the tow chain chain rupture or elongation when excessive, floating shelf moves right under the effect of pressure spring and touches travel switch until chain rupture protection collision block, and conveyer is shut down.
